ENVIRONMENTAL MANAGEMENT 5014 O LEVEL 2009
INTRODUCTION
GCE Ordinary level syllabuses are designed as two-year courses for examination at age 16 plus.
This syllabus is available for examination in both the June and November sessions.
Environmental Management is concerned with education for sustainable development in a world
where the security of resources and life-sustaining systems is endangered by human impact. It is
wide-ranging in its scope, topical in its coverage and targeted on important skills that young people
need for life.
As a syllabus Environmental Management draws upon disciplines such as Biology, Earth Science,
Geography, Economics and Anthropology. Its starting-point is the functioning interdependence of the
Earth’s natural systems, and how people use natural resources. It moves on to examine the impact of
development on the environment. Such issues as environmental pollution and resource depletion are
examined, but the view of them is forward-looking, to see how we may change the nature of
development towards future sustainability. Environmental Management is thus concerned not only
with the impact of humankind on the planet but also with the patterns of human behaviour necessary
to preserve and manage the environment in a self-sustaining way. For this reason study is linked to
the expanding areas of new thinking in environmental management, environmental economics and the
quest for alternative technologies. Case studies enable students to obtain a local as well as a global
perspective.
Environmental Management recognises that human behaviour towards the environment is guided by
the survival needs, perceptions and values of people. Underlying the syllabus framework there is a
firm recognition that cultural, social and political attitudes directly influence the economy of nature.
Environmental Management, therefore, seeks to present not only a global view of human ecology but
one in which the student is a participant as well as an observer, formulating opinion ahead of
environmental policymaking. In this direct sense the examination syllabus aims to enhance education
for sustainable development, by providing for students a deeper insight into processes and, long term,
a greater capacity for change in their knowledge, skills and values. It is a fundamental principle of the
syllabus that the achievement of sustainability will be governed by the way people think and make
decisions. A course in Environmental Management therefore calls upon young people to be
participants in defining the future of their world. In this it encourages the prospective view that ‘we
have not so much inherited the world from our parents as borrowed it from our children’.

ENVIRONMENTAL MANAGEMENT 5014 O LEVEL 2009
CURRICULUM CONTENT
INTRODUCTION
The Environmental Management syllabus can be seen as a positive educational response to the
Report of the World Commission on Environment and Development, ‘Our Common Future’ (1987:
published by Oxford University Press), commonly known as the ‘Brundtland Report’.
The Commission and the Report arose from a deep concern among world leaders and experts over
both the speed and apparent irreversibility with which the planet’s environmental resources are being
exploited.
The Commission’s main task was to come up with a ‘global agenda for change’. Its mandate spelled
out three objectives:
•
to re-examine the critical environment and development issues and to formulate realistic
proposals for dealing with them;
•
to propose new forms of international co-operation on these issues that will influence policies
and events in the direction of needed changes;
•
to raise the levels of understanding and commitment to action of individuals, voluntary
organisations, businesses, institutes and governments.
The core concept in the Report from which this Environmental Management syllabus has evolved is
that of: sustainable development. This may be defined as
‘Development that meets the needs of the present without compromising
the ability of future generations to meet their own needs.’
Two concerns are fundamentally tied to the process of sustainable development of the Earth’s
resources:
(i)
The basic needs of humanity - for food, clothing, shelter and jobs - must be met.
(ii)
The limits to development are not absolute but are imposed by present states of
technology and social organisation and by their impacts upon environmental resources
and upon the biosphere’s ability to absorb the effect of human activities. But technology
and social organisation can be both managed and improved to make way for a new era of
economic growth.
The Environmental Management syllabus is not tied to the Brundtland Report directly, but reflects its
thinking and relates to the ongoing debate that Brundtland initiated, such as the UNCED World
Summit in Brazil in June 1992. Agenda 21 of the United Nations Environment Programme (UNEP)
addresses the pressing problems facing the world in the 21st century and reflects the global consensus
and political commitment to development and environmental co-operation.

ENVIRONMENTAL MANAGEMENT 5014 O LEVEL 2009
UNDERLYING QUESTIONS
There are certain dimensions which should be considered by students as they work on examples and
case studies, whatever the issue involved, and these can usefully be phrased as questions.
•
Can the resources involved - whether they are non-living, living or human - be defined as
renewable or non-renewable in relation to the pace, scale and character of development?
•
To what extent, and why, do people use and value the same natural resource in different ways?
•
What dilemmas face individuals, communities and countries in their use and management of
natural resources?
•
How compatible and how viable are different economic approaches in tackling an environmental
issue?
•
What are the relative costs, advantages and disadvantages of different strategies for managing
the environment?
•
What are the factors influencing dispute and co-operation over the use of natural resources?
•
What are the current and potential roles of the following;
international organisations,
national and local governments,
environmental organisations,
aid agencies,
industry and commerce,
community groups,
individuals?
Impact and Management should be presented in an open-ended way. The syllabus does not
prescribe solutions as to how environments should be managed. As the Brundtland Report and its
successors such as the 1992 Rio de Janeiro UNCED conference indicate, the relationship between
environment and development is dynamic. Strategies have to be altered, adjusted and changed as
new problems arise. The same solutions may not be applicable in all regions or cases.
Students should be encouraged to look for and evaluate alternative solutions, rather than to expect or
reproduce the ‘right answer’. Students need to understand the role played by value judgements and
be able to accept that other people in their own society and elsewhere may hold values different from
their own.
Candidates should be able to show a basic knowledge and understanding of the processes listed
under Resources and Development and give examples to illustrate that understanding. With Impact
and Management, they should be able to analyse, discuss and draw conclusions based on reasoned
evidence. Teaching methods should encourage student enquiry and discussion as much as possible
and this should be based, as far as possible, on case studies, at an appropriate scale. The emphasis
should be on applying knowledge and understanding to international, national and local environmental
problems such that students are prepared to be involved in both current and future environmental
management issues.

ENVIRONMENTAL MANAGEMENT 5014 O LEVEL 2009
THE SYLLABUS MATRIX
The Environmental Management curriculum is designed to emphasise that
(a)
life on Earth as we know it is an integrated and interdependent whole;
(b)
its future is endangered by the impact of human development on natural resources;
(c)
its survival for future generations will depend on concerted action to conserve and manage the
environment as a self-sustaining resource base.
For each of the four spheres of the Earth’s environment (lithosphere, hydrosphere, atmosphere and
biosphere), the following aspects are considered.
1. Resources:
How does the natural system work?
2. Development:
How do people use natural resources?
3. Impact:
How does development change the environment?
4. Management:
How can the environment be developed sustainably?
This matrix of aspects and spheres frames the detailed curriculum objectives (page 7). It serves as a
map of the ground to be covered.
The divisions between the four spheres should not be regarded as rigid or exclusive.
Many environmental issues, e.g. water pollution, soils/agriculture, etc., involve more than one sphere.
Teachers should be aware of the links which exist between various parts of the matrix and by using
suitable cross references emphasise environmental interdependence. There are many different ways
of making a journey, using the same map: similarly, the syllabus does not prescribe a particular
sequence of study.
The approach in considering the curriculum objectives relating to resources and development should
be largely descriptive, leading to a basic knowledge and understanding of processes. It is
recommended that these should occupy some 35% of teaching time. They provide the foundation for
the analysis and discussion of impact and management, to which the remaining 65% of teaching time
should be allocated.
In the detailed curriculum, examples (in italics) are given to amplify many of the objectives. These are
to guide teachers in teaching a topic and examiners in setting papers. They are not intended to be
definitive or prescriptive, for there are a range of factors bearing on any topic and a range of possible
strategies that might follow.
It is recommended that the curriculum objectives should be covered by investigating specific examples
and case studies from both the ‘Developed’ and the ‘Developing World’.
